Cisco Switching/Routing :: GLC-GE-100FX Supported On WS-C2960S-24TD-L?
May 10, 2013
Does GLC-GE-100FX is supported on the WS-C2960S-24TD-L. I don't see this switch listed under the compatibility matrix.URL
But the datasheet for the 2960S says this:
"The Cisco Catalyst 2960-S with SFP+ does not support the GLC-FE-100BX, GLC-FE-100FX, or GLC-FE-100LX." But it provides no reference for the GLC-GE-100FX The easy answer is, no the 2960S-24TD doesn't support it, any clarification if possible.

i have an OM1 MMF fiber run between two switches, the first being a 3750 and the second being a 3550.
The link currently exceeds the maximum distance for OM1 @ 1000Mb/s (220m) so i would like to downgrade the link to 100FX using the necessary SFP's/GBIC's to extend the maximum distance to 550m and run the link @ 100Mb/s.
I have the part code for the 100FX SFP to install in the 3750 (GLC-GE-100FX) but cant find a 100FX GBIC for the 3550, can I use a 1000SX GBIC (WS-G5484) for the 3550 at one end and the 100FX SFP at the other? Any success with this configuration over MMF?

I have two 2960-s switches with GLC-FE-100FX fibre modules in and I am seeing packet loss over the link that is connected to the modules. When the interface is shutdown and brought back up it always comes up in half duplex even thought it is set to full in the config. I've seen other posts where you have to use the command no duplex then full duplex to get it to come up int full duplex. This does appear to work when I do a show int it says its full duplex however I'm stil seeing 20 - 40% packet loss on the link which suggests to me there is still a speed/duplex issue. The device at the other end is a Cisco 7200 which is set to 100Full. If I plug a Cisco 2811 into the fibre link I get zero packet loss which suggests its a problem with the switch.
I have changed the modules and fibre cables which makes no difference. As I stated at the start I have two 2960's both are showing exactly the same issue. Details of the switch are below the SFP are cisco branded:

I have recently split the voice vlan (10) from the data network (1), and am wondering why my catalysts and router do not require an interface Vlan10 statement. In the past I used OpenBSD boxes to do the routing, and I first needed to configure vlan 10 on the interface before I could get inter-vlan communication to work. With these Cisco devices it works, and I am wondering if it is because of VTP, for the fact that the ports maybe just pass all traffic, or is there some other explanation? Below is the setup, and firmware is up-to-date on all of the devices.
When I plug a phone into the POE SGE, the phone turns on, obtains an address on the proper subnet, and conversations are clear (whereas without the ip nat inside on the new subnet the calls had a lot of static). Possibly the reason that it works is because the phones properly create the tcp/ip packet, and it hops over the trunks and creates the states so that traffic routes back properly. I will install wireshark to see exactly what is going on, but is there a simple explanation that I am overlooking?

I have a network topology which you can see on image. All routers are Cisco 3745 with IOS (C3745-ADVENTERPRISEK9-M), Version 12.4(12). SW1 is L3- switch Cisco Catalyst WS-C3560E-24TD with IOS (C3560E-UNIVERSALK9-M 12.2(58)SE2). [code] After that I have problem. When PC with OS Windows 7 begins to work in corporate network, it sees "coflict ip addresses" and doesn't work with network. I've used wireshark and seen, when the PC send arp request a SW1 always send arp reply (see attached file). I think problem with command "ip sla responder", but I haven't searched information about it and I want understand this is bug or normal functioning.

I have 3560e which doesn't appear to be passing igmp traffic to the upstream router
PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server
My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (V lans 32 & 48).PC2 is a test pc on the 3560e on vlan32. 3825 is my ISPs router on vlan32.
- if i try to access the stream from PC2 it works.
- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA).
I've also captured on the ASA and i can see the igmp packet leave the outside interface but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded).the switch is running in layer 2, 12.2(35r)SE1.

I am looking for a reasonable switch but it has do do inter-VLAN Routing. I know I could go with a 3560/3750 with IP Services but I am also thinking the 2960S with IP Base IOS might do?
I have looked up the IP Base IOS and it does list IP Routing but how to actually configure inter-VLAN Routing on a 2960S with IP Base?

We have two switches WS-C2960S-24TS-L running in stack with running IOS c2960s-universalk9-mz.122-55.SE3.We have connected two checkpoint devices on Gi1/0/24 and Gi2/0/24 with a simple configuration:
interface range GigabitEthernet1/0/24, gi2/0/24
switchport access vlan x
switchport mode access
spanning-tree portfast
On the devices log we get the following message:
%SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.fe21 in vlan x is flapping between port Gi2/0/24 and port Gi1/0/24
The mac-address 0000.0000.fe21 is not found on any checkpoint interface. "Show mac-address int gi1/0/24 or gi2/0/24" does not show the correct mac-address of the checkpoint interface connected to the port, but instead shows 0000.0000.fe21.Is there a bug in the IOS, something wrong with the switch config or does it have something to do with the checkpoint config?

I have a customer with a stack of two switches C2960S-24TS-L that are running 12.2(58)SE2 universal K9, we see that the CPU load increase over time, to 95% and stays there reload solves the problem.the process that akes a lot of CPU is also the SNMP ENGINE, I see that it is running 30 minutes on 95% and then 10 minutes on 35%, this is the only stack were we see this problem. Is there also a SNMP bug in this version ?

I have a very simple setup containing 3 C2960S switches:switch 1: central switch, acting as router between VLAN 1 en VLAN 2switch 2+3: edge switches, connected via 1 link to central switch, both on VLAN 2,Clients connect to switch 2 and 3 using dhcp, switch 1 uses dhcp relay to forward requests from VLAN 2 to the dhcp server on VLAN 1. So far so good.Now I want switch 1 to add option 82 to the dhcp requests so the dhcp server can see whether the request came through switch 2 or switch 3. I tried turning on dhcp option 82 support on switch 1 by doing.

I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).

I was looking at WS-C2960S-48FPS-L (740 Watts) and WS-C2960S-48LPS-L (340 Watts) models today, I'm not sure that I understand it right,
Does WS-C2960S-48FPS-L model support all 48 ports POE+ (30Watts)? Does that mean each port will get 30 Watts on this switch?
Does model WS-C2960S-48LPS-L support 24 ports with POE and 24 ports with POE+?.

How many Switches can be stacked with WS-C2960S-48FPD-L at a max..
As per my Knowledge it is 4 and as below..
Switch 1 to Switch 2
Switch 2 to Switch 3
Switch 3 to Switch 4
Switch 4 to Switch 1
If yes then, is it mandatory to do the "Switch 4 to Switch 1" stack. why am I asking this is because this stack requires a long cable and the cable which comes with the Switch is only 0.5M.

I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

My company is beginning to have a lot of sites were we are stacking 3 to 4 C2960S-48 switche.This is making "show running-config" very very long because of the 4 x 48 interfaces.I can’t find a CLI command that show me the running-config of a ranges of interfaces. If I for example would like to see running-config for switch 3 (interfaces 3/0/1-52)The Show Running-config will show all the interfaces (for the two first swtiche = 104 interfaces), which take a time before I reach to switch 3.I miss a CLI command like: show Running-config switch 3, or module 3, or show running-config interface range x/x/x-x ?I’m well aware of the CLI command show running-config interface x/x/x, but this will only show me one interface.

I just received three WS-C2960S-24TS-Land three WS-C3560E-48TD-S switches that i entered the Express Setup on as usual. On two of each type of switch i found the default network that is used to facilitate the Express Setup was 10.0.1.1 and the others used an IP range of 10.0.2.1, i realized this is a small negligible at best difference though i need to provide management with an answer as to why there is a difference between the two and can’t find anything online as to why there is a difference or something that proves there should be a difference. All the documentation I find sounding Express Setup notes that the IP range will be 10.0.1.1 not 10.0.2.1

Are there any differences between the autoqos commands on a WS-C2960S switches (or in any other series)? Follow the commands:
- auto qos trust
- auto qos voip trust
I was checking the documentation on this link:
URL
And couldn't find any great difference between the two commands, as far as I could see they'll set the Ingress and Egress queues the same way.
Are there any differences between those two commands (auto qos trust and auto qos voip trust)? If so, when should I use one and the other?
